Yes, Trinity Force has a Super-Unique* Passive that behaves identically to Sheen's, only with a 150% damage increase on the next hit instead of 100%. In addition, it gives the components of all three component "swords" (Sheen, Phage, Zeal) in an increased amount: HP, MP, Attack Damage, AP, Move Speed, Attack Speed, Crit Chance, Slow on Hit.
*It is Super-Unique in that it does not stack with the Unique Passives of Sheen or Lich Bane. Boots are the only other Unique Passive to not stack with different item's passives of the same type.
Also @Max, there is no way to have "No Cooldown", as Cooldown reduction caps at -40%. Additionally, Sheen/Lichbane/Triforce all have a cooldown of 3 seconds on their ability, meaning even if you are spamming spells faster than that somehow (Like Hate Spike on Eve), you don't get multiple procs of Sheen/Lichbane/Triforce in a row.
